Enum cogl::IndicesType

#[non_exhaustive]
pub enum IndicesType {
    Byte,
    Short,
    Int,
    // some variants omitted
}

You should aim to use the smallest data type that gives you enough range, since it reduces the size of your index array and can help reduce the demand on memory bandwidth.

Note that IndicesType::Int is only supported if the FeatureID::OglFeatureIdUnsignedIntIndices feature is available. This should always be available on OpenGL but on OpenGL ES it will only be available if the GL_OES_element_index_uint extension is advertized.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Byte

Your indices are unsigned bytes

Short

Your indices are unsigned shorts

Int

Your indices are unsigned ints
